Subject: [PATCH 092/182] ARM: dts: qcom: Update msm8960 device trees

* Move SoC peripherals into an SoC container node
* Move serial enabling into board file (qcom-msm8960-cdp.dts)
* Cleanup cpu node to match binding spec, enable-method and compatible
  should be per cpu, not part of the container
* Drop interrupts property from l2-cache node as its not part of the
  binding spec
* Add GSBI node and configuration of GSBI controller
